About this space

Built in 1892, the Pioneer Building housed mining companies during the Klondike Gold Rush and Seattle’s first speakeasy during Prohibition. The Richardsonian Romanesque-style building earned National Historic Landmark status in 1978 and borders Pioneer Square Park. A flagship property for Expansive on the West Coast, it offers six floors of stunning workspace with hardwood floors, cast iron columns, and a large center atrium lit by skylights running the length of the building.

It is rare to find a place that to work that invites you to feel comfortable and confident like your own home.. That is Vickii and her team at Pioneer Square — WFH vibes, when you can’t WFH.. I am grateful for this amazing team and Vickii’s leadership. Without it, we would have ended up in a sterile work environment.. Today we had a hot chocolate station, so naturally, I made a mocha with the provided coffee!

Having a home base to return to after a long week of being in the field is invaluable. Expansive at Pioneer Square has an excellent mix of support, solitude, collaboration, and quiet to work in. No matter the time of day or time of week I swing through, there are smiling faces, social events, and a welcoming environment for me to focus and enjoy my work.. Thank you for providing a fantastic place to thrive!
